Srimad Bhagavatam Canto 10, Chapter 72, Text 05

SB 10.72.5

tad deva-deva bhavatas caranaravinda-
 sevanubhavam iha pasyatu loka esah
ye tvam bhajanti na bhajanty uta vobhayesam
 nistham pradarsaya vibho kuru-srñjayanam
Therefore, O Lord of lords, let the people of this world see the power of devotional service rendered to Your lotus feet. Please show them, O almighty one, the position of those Kurus and Srñjayas who worship You, and the position of those who do not.
Here we clearly see the heart of a preacher. The great devotee Yudhisthira Maharaja implores Lord Krsna to demonstrate plainly the result of worshiping Him and the result of not worshiping Him. If the people of the world could understand this, they could begin to recognize that Krsna is the Supreme Personality of Godhead and that everyone’s ultimate self-interest lies in surrendering to Him. As confirmed by great authorities, Yudhisthira Maharaja is a pure devotee of the Lord, and thus his actual motivation in discharging his duties as a king was to establish the supremacy of Lord Krsna as the Supreme Personality of Godhead. This is the real purport of the activities of the Pandavas, which are described in both the Srimad-Bhagavatam and the Mahabharata.
